Title: Integrated type semiconductor laser
Inventor: TAKAMURA TAKASHI
IPC: H01S5/00
Filed: 1988-01-29
Abstract: PURPOSE:To enable an integrated type semiconductor laser with high-output and low-noise characteristics to be obtained by providing two or more laser beam emitting parts and by enabling reflection index waveguide path width to be fully wider than current injection width at the center of one resonator out of the laser beam emitting parts. CONSTITUTION:A rib waveguide type laser 101 and a multiple-mode oscillation laser 102 are integrated. In one laser, the stripe width is equal at both edges and center. On the other hand, in the other laser, the center is fully wide for constituting 2-beam integrated type semiconductor laser. For example, the stripe width of the laser 101 is 3mum and the stripe length is 250mum. Also, the stripe width at the center of the laser 102 is 15mum, that at both edges is 3mum, the stripe length at the center is 150mum, and that at both edges is 50mum each. When using this 2-beam type semiconductor laser for an optical magnetic disk, use of the low-threshold and highly efficient laser 101 for writing and that of the laser 102 with low-noise characteristics for reading allows for low drive power and use of 2 beams enables error correction to be made at high speed.

Title: Electrostatic powder spray gun with hose purifying adaptor
Inventor: TERENSU EMU FURUKAASON
IPC: B05B5/025
Filed: 1994-02-16
Abstract: PURPOSE: To solve the problem of powder accumulation in the flow path of an electrostatic spray gun by introducing air for purging into a hose line and removing the accumulated matter of the powder from the powder flow path of the hose line and the powder flow path of a barrel. CONSTITUTION: In the case of electrostatic spraying of the powder supplied to the gun 10 via a hose 21, electrostatic separation occurs in some cases in consequence of the different molecular surface structures of the individual powder particles. Some of these different particles accumulate on the inside surface of the powder flow path in the gun 10 until finally electrostatic charges can no longer attract the accumulated particles to the inside surface of the gun 10, and a soft mass of the powder peels, as a result of which, a defect arises on the surfaces of the parts to be coated. Before such accumulation grows and increases, the spraying is once suspended and the compressed air from an air hose 87 is passed through the flow path of the hose portion 20, and further, the flow path of the gun 10, and the accumulated particles are removed from these flow paths. The electrostatic powder spraying can be continued again after the end of purging.

Title: Semiconductor logic circuit device
Inventor: FUJII TOMOKO
IPC: H01L27/06
Filed: 1990-01-29
Abstract: PURPOSE:To eliminate the need for matching the logic threshold voltage of an input circuit with a TTL level in varying a ratio of a CMOS gate even for the input signal of the TTL level by providing a circuit shifting the voltage of an input signal. CONSTITUTION:An input buffer section has a level shift circuit comprising a PNP transistor(TR) 3 and diodes 4, 5, its base input is connected to the output of an input protection circuit 2 and the output is connected to the gate of a PMOSFET 9 of the input circuit. On the other hand, the gate of an NMOSFET 8 is connected directly to the output of an input protection circuit 2. Thus, a signal inputted from an input signal pad 1 is inputted to the gate of the PMOSFET 9, then the signal is shifted positively by a voltage depending on the level shift circuit. Thus, even when an external input signal is the input signal of a TTL level, it is not required to match a logic threshold voltage of the input circuit with the TTL level by varying a ratio of the CMOS gate.

Title: Slide type hinge
Inventor: SAWADA YUTAKA
IPC: E05D3/06
Filed: 1995-02-08
Abstract: PURPOSE: To achieve the cost reduction of a slide type hinge by pressing the opening cam surface or the closing cam surface of a positioning member provided to a hinge, when a door whose upper end has been pivotally supported is opened or close, so that the opened posture or closed posture can be maintained. CONSTITUTION: When a door is closed, a second fitting member 13 that has been fitted to the upper end part of the door takes up such a posture that it is bent by 90 degrees with regard to a first fitting member 11 that has been fitted to the upper peripheral part of the opening part of a housing body. Then, a second cam surface 42 is pressed through an abutting plate 18 by means of the pressing force of a compression spring 17, and the door becomes such a condition that it has been pressed against the housing body side. When the door is opened, the cam part 16 of a positioning member 15 is oscillated, and also the cam surface abutting on the abutting plate 18 shifts from the second cam surface 42 to the first cam surface 41.  Since the cam surface 41 is pressed, the door is pressed to take a horizontal direction, and the downward oscillation due to the own weight of the door can be prevented. Thus, the mechanism for maintaining the opening posture or the closing posture of the door can be integrated with the hinge, and also space saving can be achieved.
